Setting Description
Bitmap cache file size in unit for
number bpp bitmaps
Specifies the size of the bitmap cache, in kilobytes or megabytes, to use
for specific bits per pixel (bpp) bitmap color settings.
Separate versions of this setting are provided for the following unit and
bpp combinations:
n
KB/8bpp
n
MB/8bpp
n
MB/16bpp
n
MB/24bpp
n
MB/32bpp
Bitmap caching/cache persistence
active
Determines whether persistent bitmap caching is used (active). Persistent
bitmap
caching can improve performance, but it requires additional disk
space.
Color depth
Specifies the color depth of the View desktop. Select one of the available
settings:
n
8 bit
n
15 bit
n
16 bit
n
24 bit
n
32 bit
For 24-bit Windows XP systems, you must enable the Limit Maximum
Color Depth policy in Computer Configuration > Administrative
Templates > Windows Components > Terminal Services and set it to 24
bits.
Cursor shadow
Determines whether a shadow appears under the cursor on the View
desktop.
Desktop background
Determines whether the desktop background appears when clients
connect to a View desktop.
Desktop composition
(Windows Vista or later) Determines whether desktop composition is
enabled on the View desktop.
When desktop composition is enabled, individual windows no longer
draw directly to the screen or primary display device as they did in
previous versions of Microsoft Windows. Instead, drawing is redirected
to off-screen surfaces in video memory, which are then rendered into a
desktop image and presented on the display.
Enable compression
Determines whether RDP data is compressed. This setting is enabled by
default.
Enable Credential Security Service
Provider
Specifies whether the View desktop connection uses Network Level
Authentication (NLA). In Windows Vista, remote desktop connections
require NLA by default.
If the guest operating system requires NLA for remote desktop
connections, you must enable this setting or View Client will not be able
to connect to the View desktop.
In addition to enabling this setting, you must also verify that the
following conditions are met:
n
Both the client and guest operating systems support NLA.
n
Direct client connections are enabled for the View Connection Server
instance. Tunneled connections are not supported with NLA.
Enable RDP Auto-Reconnect
Determines whether the RDP client component attempts to reconnect to
a View desktop after an RDP protocol connection failure. This setting has
no effect if the Use secure tunnel connection to desktop option is enabled
in View Administrator. This setting is disabled by default.
NOTE RDP auto-reconnection is supported for desktops running View
Agent version 4.5 or later only. If a desktop has an earlier version of View
Agent, some features will not work.
